In modern construction, rebar couplers have become essential for connecting reinforcing bars, enabling structures to achieve higher safety standards and efficiency. TCR Engineering Services, a premier materials testing laboratory based in Mumbai, leads the way in advanced performance evaluation of rebar couplers. Working closely with leaders like Dextra, Ashoka Buildcon, and Leviat, TCR ensures that projects, including those on National Highways and in Saudi Arabia, meet stringent quality standards.
Our testing capabilities are extensive, covering a wide range of rebar coupler evaluations as per the Bureau of Indian Standards (IS 16172). From static tensile, slip tests, and spectrochemical analysis to high-cycle fatigue testing of up to 2 million cycles, we ensure that couplers meet dynamic site conditions. Testing is performed on 12mm to 40mm rebar joints, with additional mechanical testing for TMT bars from 16mm to 45mm diameter.
TCR’s commitment to quality extends to the latest technologies and high-precision equipment, including a closed-loop servos hydraulic dynamic UTM machine, enabling fatigue testing with a frequency range of 0.035 to 30 Hz. Our NABL accreditation (ISO/IEC 17025:2017) confirms our adherence to both local and international standards like ASTM A1034 and ISO 15835-2.
The shift towards precast construction has further propelled demand for reliable couplers, which reduce rebar congestion and improve site efficiency. TCR’s rigorous testing protocols ensure compatibility and performance under both static and dynamic loading conditions, meeting the growing needs of modern infrastructure projects.
With nearly 50 years of experience, TCR Engineering stands as a trusted partner in ensuring that every splice, connection, and joint upholds the highest safety standards in the industry.
